Factors Of Size Reduction Equipments

CHAPTER 20: SIZE REDUCTION – EQUIPMENT FOR SIZE

• Size reduction is achieved by impact of the balls when they dropfrom near the top of the shell • Energy consumed in lifting the balls is utilized for grinding job • When the ball mill is rotated, the balls are carried by the mill wall nearly to the top • Balls are released by the gravitational pull and drop to the bottom and picked up again • Centrifugal force keeps the ball in contact with the

Size Reduction - an overview ScienceDirect Topics

Particle size reduction is accompanied by increasing specific surface area to volume relationships. This may be demonstrated by successively reducing a cube of 1 cm/side into smaller cubes of 0.1, 0.01, 0.001 and 0.0001 cm sides respectively (Fig. 4.3).
